Our invention relates to building walls and consists in a novel buildingblock structure and assembly. u' u One of the most desirable, artisticand attractive forms of building walls is that having a front faceformed ofrough stone blocks of irregular size and shape laid with brokenjoints both longitudinally and vertically of the wall. Due totheVscarcity of suitable l@ building stone in many localities and theincreasing cost of quarrying and transporta- 'Y tion, the expense of awall as described above is greater than the cost of a wall formed otartificial stone'blocks7 but no artificial stone blocks have yet beenproduced which will simulate a natural stone wall of the Vtype referredtoV abovevi. e.,' presenting a broken ashler appearance. j

One of the objects of our invention isto provide an artiiicial stonewall formed of blockshaving varying height and width and producing abroken ashler finish similar to that produced by roughstone.

Even when rough `natural stone has been used to form a wall face it hasbeen customary to fill in behind the face stone with rough irregularstone or rubble and, in many instances, to dump sand and old mortar intothe spaces, which practice results in a weak Another object of ourinvention is to provide artificial stone blocks of suiiicient depth toextend through the wall in which they are used from front to back ot`the wall,` each block having a'rough stone faceat one end and a smooth:tace at the opposite end and the side and top and bottom faces of thewallv also being smooth.

In laying a stone wall it is necessary `for the mason to trim many ofthe stones inorder to it them in between the adjacent stones.V This is atime consuming and expensive proc-v ess, and it is a further object ofour invenming of the blocks in and unsatisfactory wall subject todeterioration to provide a series of artificial blocks of varying heightand width which may be assembled after a predetermined design to producea broken ashler nish without the necessity of any Vtrimming with thepossible eXception of cutting the blocks to itaround window or dooropenings.

Another object of our invention Vis to provide in a wall of the typedescribed a cor- Lner construction which will lend itself to 50:forminga well bonded joint between two iiitersecting walls formed ofthe series of blocks referred to and without requiring any .trimlorder'to complete the corner construction. Thesey and other de- 05tailed objects of ourinvention are attained Y in the structureillustrated in the accompanying drawings forming apart ofthe-specification 1n which:

Figiire 1 is an isometric view of an artii- 70 cialvstone wall showingone `corner thereof.

Figures- 2 and 7 are horizontal sections taken on the correspondingsection lines of Figure 1.

. The corner blocks 1, 2 `and 3 yhave square ,7 bases, the width ofblocks 1 and 3 being greater than the width of block 2 so that the sur-Jface presented by the three corner blocks in ythe direction of wall Ais irregular.k Since blocks 1, 2 and 3 have square bases, thesur- 80face presented in the direction of wall Bwill `be. identical with thatpresented in the direction of wall A@ At the side: of block. 1l arel twosmaller blocks 4 and 5, the combined height of which plusthe layer ofmortar 6 equals the height of block 1, but the widths of blocks 4 and 5dier. f Y, f v i Above block 5. and overlapping the'joint' between thesame and block 1 is block 7.and 90 above block 7 is a block 8 Lot"different height and width, the combined heights of 'block 7 andl block8 plus the layer of mortar 9 equals the height of block 2.

Above 8 is a small block 10 and above'l to present irregular surfaces inthe directions of both of said walls, the Vcontours of said surfacesbeing the same,V saidy corner blocks varying in their horizontaldimensions, and blocks eacli of greater depth than said corner blocksoverlapping each other at the-rear of said corner blocks, certain ofsaid blocks of greater depth overlapping the larger corner blocks,thereby binding the corner blocks with resp ect to each other and keyingthe two walls together.

3. In a wall construction, two walls intersecting to form ak corner, aseries of corner blocks arranged one above the other and cooperating topresent irregular surfaces in the directions of both of said walls, thecontours of said surfaces being the same, and blocks each of greaterdepth than said corner blocks but of various heights up to height ofcorner 20 blocks, a block in one wall overlapping a block in the firstlayer in the other wall at the rear of said corner block, said block inthe second mentioned wall overlapping a block in the second layer in thefirst mentioned wall at the rear of said corner block, said alternationin the overlapping of said blocks being carried to the top of the wall.

4. A building wall of preformed artificial stone blocks of a limitednumber of sizes assembled in a series of uniformly constructed unitshaving a cruciforin outline disposed symmetrically about vertical andhorizontal axes of the unit, successive units being in inverted relationto each other, and intermediate units of dumb-belllike contourcooperating with said cruciform units to form a continuous wall face theadjacent blocks of which are of diiferent widths and heights to producea patterned wall having the appearance and bonding effectiveness ofbroken ashler masonry.

5. In a building wall, a series of uniformly constructed units; eachunit comprising a plurality of blocks each of which is adjacent toothers of different width and height, said with joints in the adjacentdumb-bell units Y joints of each cruciform unit being disposedasymmetrically of the horizontal axis of the unit and alternatecruciform units being inj verted whereby the uniform contour andstructure of duplicate units is rendered unnoticeable and a wall isproduced havingthe appearance and bonding effectiveness of broken ashlerconstruction.

In testimony whereof we hereunto affix our signatures this 27th day ofApril, 1929.
